SOAP SUPPLY FOR SCRUBBIN'G MACHINES.

Application filed April 20, 1927.

This invention relates generally to new and useful improvements in floor scrubbing machines and has more particular reference to a soap supply for any conventional type of scrubbing machine for enabling soap to be delivered to the floor adjacent the machine whenever the same becomes necessary, and this without stopping the operation of the machine or its movement over the surface being cleaned.

In carrying out this invention there is provided a soap container that may be easily supported in position above the'iioor and having communication with a discharge nozzle rigidly attached to the handle of the machine in such a manner as to be di posed adjacent the scrubbing mechanism, a valve being provided to permit the flow of the soap which is of the fluid character, to be discharged onto the floor as required.

In further carrying out my invention means is provided adjacent the handle of the scrubbing machine to permit of the controlof the valve without releasing the handle and without bending over, or without removing the attention from the work at hand. In the drawing wherein like reference characters indicate corresponding parts throughout both of the views:

Figure l is a side elevation of my im proved soap supply for conventional types of scrubbing machines, the handle of a machine being disclosed in dotted lines and to which the niajor-structural elements of the present ii'ivenlion are attached, and

i igiue 2 is a horizontal section on an enlarged scale taken substantially upon the line 2-2 Figure 1 for more clearly disclosing the manner oi? attachment of certain of the units of the invention to said scrubbing machine handle.

Now having particular reference to the drawing A in Figure 1 designates a handle of a conventional scrubbing machine disclosed in dotted lines. In carrying out my invention there is provided a liquid soap container 5 that is to be suitably supported above the surface being scrubbed, and that is provided at its lower end with a discharge nipple 6 to which is attached one end of a predetermined length of flexible hose 7. The invention further consists of a length of rigid pipe 8 to one end of which is con- Serial No. 185,218.

nected the other end of the flexible hose 7 and to the lower end of which is connected a horizontal pipe section 9 within which is arranged a suitable valve 10 from which leads a depending discharge pipe 11.

The stem of said valve 10 is operatively associated with a relatively elongated rod 12 arranged in spaced parallel relation with the pipe 8 and terminating at the upper end of the pipe and into a suitable handle 13.

For facilitating the attachment of the rod 12 and pipe 8 to the scrubbing machine handle A, a plurality of fastening means is provided, preferably three in number and designated generally by the reference character 14. Each fastener consists of a single length of metallic strapping bent upon itself for providing a loop 15 for engagement around the scrubbing machine handle A and around the rigid pipe 8. The sides of the said length of strapping in front of the pipe 8 are then rigidly connected by bolt and nut fasteners 1616. The outer fastener is arranged slightly within the ends of the sides 01 the strap, while said ends are curved to provide a clamp 17 for receiving the valve control rod 12, but this in such a manner as to permit of the easy turning of the rod by reason of the handle 13.

It will thus be seen that I have provided a highly novel, simple and inexpensive soap supply attachment for any conventional design of scrubbing machine that is well adapted for all the purposes heretofore designated, even though 1 have herein shown and described the invention as consisting of certain detail structural elements, It is nevertheless to be understood that minor changes may be made therein without affecting the spirit and scope of the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is In a soap supply attachment for scrubhing machines of the character including the manipulating handle, a rigid pipe at-' tached to the handle of the machine, a soap discharge nozzle arranged at the lower end of the pipe, a valve between the nozzle and pipe at the lower end thereof and a valve control. rod extending upwardly from the valve in spaced parallel relation with said pipe and means for rigidly securing the pipe the strap in front of said pipe, and jaws at to the handle and for supporting the valve the ends of the strap for providing ehearcontrol rod in such a manner as to permit ing for the valve rod. the turning of the SfLlTlG, suidn'ieztns co'nsist- In testimony whereof I have affixed my 5 ing of a single length of metal strapping signature.

bent intermediate its ends around the handle and pipe, fasteners connecting the sides of WVILLIAM Vi.- MCFALL.
